How to win the game

I usually start at wolfs then get blue then wraiths. After that i start ganking usually top or mid then bot last if i can. Pretty much after this as long as my team does not screw up and feed we can win. As for items i always get a wrings first. Then if ganking is going good i can go back and get my merc treads and witts end at the same time. Then warmogs and atmas for tanking and doing tons of damage. Then for the last two you can get what ever you want to help your team win the game. Most of the times i just get force of nature and randion's omen, but if they have a ton more ap then ad ill just get something else for magic resits or dps items.
